Prebuild binaries: more detailed setup info/parameters (busybox/aboriginal) ?

[piquemal michel]

Hi,
I'm trying to build a "small" static busybox for my embedded system (mipsel).
As a starting point, I used pre-built mispsel binaries, from
http://www.busybox.net/downloads/binaries/latest/
which worked straight out-of-the-box: great!

Now I wanted to build my own.
README file says it's built with Aboriginal (with no more detail on images version, use pre-built?, compiler flags?, etc)
So I picked-up pre-built Aboriginal system-image-mipsel, and built an defconfig busybox for test.
While my resulting defconfig busybox works on that image, it segfaults on my target.
(tested with several aboriginal images, etc.)

I assume there's magic options/flags used to build those busybox prebuilt-images on Aboriginal, or subtle things on the way you build your aboriginal images: busybox make defconfig does not seem to cover it all.
Could you please share those, and eventually document it further in FAQ and/or README file in the future?

Many thanks for all the hard work!
